There is still no confirmation of anything at this point (which is why I haven't yet posted, because I, you know, wait for hard information before racing to the keyboard), but the Navy Yard has been on lockdown since before 8 am after reports of shots fired. There is a massive police (and media) presence on M Street, road closures everywhere, and helicopters circling, but still no official word one way or the other.

Will post updates as needed, though as I am hitting the Post button, reports are coming out that no injuries have been found and that "all indications are no shooting."
